Demon Hunting City

There are countless earths in the multiverse, but each earth cannot escape the fate of destruction. The administrators of the Demon Hunting City will take away the humans who are about to disappear with their world, and continue to live as hunters in this place beyond time and space. The value of their existence is to clean up the pollutants that bring destruction to parallel earths for the immortals. As hunters, they must constantly travel to different doomsday earths, or participate in polluted spiritual world games, in order to survive in this cruel and ruthless nightmare city...
